Hot on the heels of the track only 2-Eleven, Lotus decided to follow it up with an even more track-focused offering. So they've given us this, the Exos Type 125.
It comes with a 645bhp, 10,800rpm 3.5-litre Cosworth V8 and a carbon fibre monocoque. That means it's got close to 1000bhp per tonne. Apparently the lump will last 3000 miles between rebuilds, too (Positively astronomical service intervals... - Ed).
Owners also get access to the exclusive 'Exos Club' - an organisation which will run track events with racing and fitness instructors as well as mechanical support.
Unlike 'regular' F1-esque track specials, the Exos doesn't need a full pit crew to start it up. You can fire up the engine from inside the cockpit.
Only 25 will be built and they'll each cost in excess of £600,000 - so you've got to really want one over, say... three Ferrari 458s, a phalanx of Evoras, or a pair of Zondas...
Deliveries start in spring 2011.
